Compounds of the formula ##STR1## where X is OH, NH.sub.2, SH, OR or SR (where R is alkyl of 1 to 4 carbon atoms or benzyl), R.sup.1 is H or alkyl of 1 to 8 carbon atoms, R.sup.2 is H or methyl, Y is the salt of an amine of the formula ##STR2## where R.sup.3 and R.sup.4 are lower alkyl, e.g., 1 to 4 carbon atoms and n is an integer of 2 to 4 with p-acetamidobenzoic acid and where z is a number from 0 to 10 are useful as immunomodulators, as antiviral agents and in specific cases have anti-leukemic activity. The compounds and compositions where z is 1 to 10 are novel per se. When R.sup.2 is H the presence of Y enhances the immunoregulatory activity and the antiviral activity. If X is the NH.sub.2 there is immunoinhibitory activity but no immunostimulatory (immunopotentiatory) activity.
式为##STR1##的化合物,其中X为OH、NH.sub.2、SH、OR或SR(其中R为1至4个碳原子的烷基或苄基),R.sup.1为H或1至8个碳原子的烷基,R.sup.2为H或甲基,Y为式为##STR2##的胺盐,其中R.sup.3和R.sup.4为较低的烷基,例如1至4个碳原子,n是2至4的整数,与对乙酰氨基苯甲酸结合,其中z为0至10的数字,可用作免疫调节剂、抗病毒剂,并在特定情况下具有抗白血病活性。其中z为1至10的化合物和组合物本身是新颖的。当R.sup.2为H时,Y的存在增强了免疫调节活性和抗病毒活性。如果X为NH.sub.2,则具有免疫抑制活性但没有免疫刺激(免疫增强)活性。
